will be underfloor heating regardless of which heating method, I don’t think Heatpumps work particularly well on rads, need to start oversizing them and considering aluminium rads. But never going to be same as the heat distribution from underfloor and it’s a smaller emitter surface area...

wont be exactly £6k for each. but material cost isn’t far off give or take. just over 10kw worth of panels, 8kw inverter comes to a few £ over £5000, then add all the isolators, fixing kit for the roof, cabling and other misc parts and £6k probably isn’t too far off. then look at a 9kw split...

Will have a read, this was my original plan, heat pump then add solar later on. as long as I’m living in the house it’s fine, we will leave it running all day off the thermostat so it just keeps house a constant temperature... like we do now with nest, it sits on 23 and just tops up the heat...

It is the cost to buy that is about the same as solar. install as long as it’s mono block can be done as a diy install as it just hooks up to heating circuit in place of boiler.

No about same as solar to buy, running costs are about same as gas if sized and installed properly

true, but with a monoblock it’s only 1 feed and return which hooks up in place of boiler. Would just need an electrical feed put in. If anything a mono block is probably easier to install than solar.

not really interested in the return on investment part presently, because if I rent out this house eventually, I won’t be gaining from it anyway... just need something which will give me a solution to try and get away from fossil fuelled heating, and mean electric bills aren’t sky high for...

I know that lol, but it means that it will generate maximum it can given weather conditions because it will continue to capture sunlight as the sun moves across the sky, vs if it’s installed on east facing roof only... after midday it will drop off as the sun moves to the west side of the roof...

Thanks, that’s the thing I’m still new to this myself and haven’t got first hand figures, only assumptions based on what I’ve seen other people achieving but they aren’t all accurate because 10kw isn’t common, most seem to be around 3-4.5 or thereabouts. so all information appreciated. still...

My interpretation, is that a 1kw system generates at a rate of 1 kw per hour. same as a 1 kw appliance uses electric at a rate of 1 kw per hour apologies though the way I wrote the terminology as kw/h rather than kWh. I could be disappointed, but I would expect more than 1.5kw per hour from...

nope more expensive. Should be able to in most cases do it with 1 inverter. but it depends on the panels you have and their total volts and amps and the inverter... I don’t know how true but was told it’s a good practice thing to have 1 per array so a roof with 2 sides would under that case use...

I haven’t looked into how it works completely. but it senses the export with a CT clamp. If you create a demand by switching on something electrical, I’d imagine it senses the export has dropped and it ramps up the output to match demand, so if you was using hypothetically a full 10kw demand...

haven't worked this out, but cost wise, panels are around about, £3298 roughly (dependant on shipping costs) for 10kw worth of 400W Bifacial panels in bulk direct from China distributor. then rest of the cost would depend on choice of inverter But 2x 4kw solis inverters are around around...

that limit is only for export. If you limit export to 16amp / 3.6kw there is no limit on the size. I’m looking to install around 10kw, basically want to fill both sides of the roof with panels to offset running costs of a 9kw electric boiler. Im going to do a G98 with the DNO anyway to see...

I don’t know yet. I did price it up with midsummer, but then found ITS technologies cheaper. but I’ve since made enquiries sourcing the quantity of panels I want direct from China from a JA solar distributor and even with tax it’s cheaper still and they sell 400W Bifacial JA solar panels, which...

Thanks, so if I get a structural engineer to provide calculations, and then submit then under a building notice for part A and get it inspected will that cover that then? I would use an MCS certified person, but they won’t sign off something they haven’t installed and I want to supply my own...

Looking to install some solar PV, but understand it needs building notification. just wondered what notifications I need to make and if anybody had any experience getting it signed off. not worried about MCS Export guarantee payments. electrical will be covered as property is being rewired so...
